Could you attach an image of the slope? Because i dunno what lesson you're on....
:/
Answer: y=-x-2
Slope intercept form is written as y=mx+b, with m being the slope and b being the y intercept.
The slope is negative one. To find the slope, use the formula y1-y2/x1-x2. When you substitute, you may get -4-1/2-(-3). When you solve it, you get -5/5, or -1.
To find the y intercept, look where the line crosses the y axis (vertical line). In the graph, it crosses as -2. Substitute these numbers into the equation and you get y=-1x-2 which can be simplified to y=-x-2.
The angles are the same magnitude so set them equal to each other and solve for x.
15x = 12x + 15
3x = 15
x = 5
Then plug 5 back into one of the angles.
12(5) + 15 = 75
ANSWER: 75°
Since both sides have a -2 in then you can pull it out making the equation -2(3*4) which equals -2(12) so A is correct
If he hikes another 2 km, he will be halfway there.
17+2= (1/2)x
19=(1/2)x
38=x
Final answer: The total length of the hike is 38 km
